Ah, my wife's a fellow at St. Jude's. Right now Krav works well because it has a solid group that does afternoon classes, which I can usually make with my schedule. The fight classes are fun (gloves, helmet, shin pads), and I think it's a good introduction to the hands side of striking. I'm still transitioning away from the bad habits I picked up in TKD...

I train at St. Jude. It's a small group of us science geeks with shitty work hours! I trained a couple of times at Memphis BJJ and it's really a great place. I recommend checking them out. The problem for me was the yearly contract. Scientists don't get paid much :) I think next year if I get my bonus I'll try and head back to Memphis BJJ: they have a good facility + boxing coach you can work with etc.

I think my mate Chris is a Lvl II at your Krav school (or was til he dropped out for the summer).
